Structural Behavior of High Strength Arched Reinforced Concrete Slabs

In the past, arch represented one of few structural systems which provide a possibility to cover large spans. Nowadays, same importance is presented as need increased with increase construction spans and arched structures are constructed in different shapes from various materials such brick, steel reinforced concrete. The main aim this study was investigate behavior ultimate strength concrete slab under flexural load. parameters considered present investigation are, mix compressive strength, thickness slab, area steel, curvature support conditions. A total fourteen samples tested two-point observed by reading deflection at mid-span observing crack patterns strains top bottom fibers. linear up first cracking load still (35% - 55%) load-deflection curve mid span may be idealized bilinear curve. increasing 116% leads (15% 25%). Increasing 43% (6% -17%). 45% (29% 34%). 200% 28%). Changing simply pin-pin (200% 245%).
